Electrical connector

Abstract

An electrical connector includes an insulating body, multiple terminals, a metal member, and a metal shell. The insulating body has a base and a tongue extending forward from the base. The terminals are fixed in the base and exposed to upper and lower surfaces of the tongue. The terminals include at least one ground terminal. The metal member is fixed on the insulating body. The metal member bends backward and extends to form an elastic arm. The elastic arm presses the ground terminal. The elastic arm has a protrusion portion, and the protrusion portion is higher than the top surface of the base. The metal shell wraps a periphery of the insulating body and the metal member. The protrusion portion urges the metal shell, to enable a stable electrical connection between the metal member and the ground terminal, so that the electrical connector has good high frequency transmission performance.
